Definitions
- the invention relates to a partially neutralized, anionic (meth) acrylate copolymer, a medicament form coated therewith, processes for preparing the drug form and the use of the partially neutralized (meth) acrylate copolymer for the preparation of a medicament form which rapidly releases the active ingredient at a specific pH.
- EP 0 088 951 A2 describes a process for coating drug forms by means of a coating agent dispersed in water.
- the partial neutralization of the carboxyl groups is recommended.
- Salification of the acidic groups occurs by reaction with a base.
- Bases are alkalies, e.g. Caustic soda, potassium hydroxide, soda, potash, sodium bicarbonate, trisodium phosphate, trisodium citrate or ammonia or physiologically acceptable amines, such as triethanolamine or tris (hydroxymethyl) aminomethane into consideration.
- Redispersing is a degree of neutralization of from 0.1 to 10% by weight of the carboxyl groups contained in the copolymer.
- WO 2004/096185 describes a dosage form and a process for its preparation.
- the pharmaceutical form is coated with an anionic (meth) acrylate copolymer, which can be partially neutralized if necessary.
- an anionic (meth) acrylate copolymer In order to prepare a solution of the anionic copolymer, a partial or complete neutralization of the acid groups is usually necessary.
- the anionic copolymer may, for. B. gradually in a final concentration of 1 to 40 wt .-% are stirred into water and thereby partially or completely neutralized by addition of a basic substance such. As NaOH, KOH, ammonium hydroxide or organic bases such as. B. triethanolamine.
- Anionic (meth) acrylate copolymers e.g. B. EUDRAGIT ® L, EUDRAGIT® L100-55, EUDRAGIT® S or EUDRAGIT® FS, are known as enterosoluble coatings for dosage forms.
- the anionic (meth) acrylate copolymers are characterized by specific dissolution pH values in intestinal juice or in artificial intestinal fluid.
- the specific dissolution pH values or the pH values of the specific beginning of the dissolution are in the range of z. B. pH 5.5 to 7.5. From the specific for the respective anionic (meth) acrylate copolymer dissolution pH and above so coated drug forms release the active ingredient contained.
- the specific dissolution pHs thus characterize the onset of drug release.
- anionic (meth) acrylate copolymers in partially neutralized form. This results in an improved solubility of the polymer in Water and stabilization of the polymer dispersions achieved.
- bases for the partial neutralization substances such as NaOH, KOH, ammonium hydroxide or organic bases such. As triethanolamine, recommended.
- the object is achieved by a partially neutralized anionic (meth) acrylate copolymer consisting of free-radically polymerized units of 25 to 95 wt .-% of Cr to C 4 - alkyl esters of acrylic or methacrylic acid and 5 to 75 wt .-% (meth ) acrylate monomers having an anionic group, wherein 0.1 to 25% of the contained anionic groups are neutralized by means of a base,
- the base is a cationic, organic base having a molecular weight above 150.
- the invention relates to a partially neutralized, anionic (meth) acrylate copolymer.
- the anionic (meth) acrylate copolymer consists of 25 to 95, preferably 40 to 95, in particular 60 to 40 wt .-% of radically polymerized Cr to C 4 alkyl esters of acrylic or methacrylic acid and 75 to 5, preferably 60 to 5, in particular 40 to 60 wt .-% of (meth) acrylate monomers having an anionic group.
- the proportions mentioned add up to 100% by weight.
- small amounts ranging from 0 to 10, e.g. B. 1 to 5 wt .-% of further vinylic copolymerizable monomers, such as.
- hydroxyethyl methacrylate or hydroxyethyl acrylate may be included.
- no further vinylically copolymerizable monomers are contained.
- C 1 to C 4 alkyl esters of acrylic or methacrylic acid are in particular methyl methacrylate, ethyl methacrylate, butyl methacrylate, methyl acrylate, ethyl acrylate and butyl acrylate.
- a (meth) acrylate monomer having an anionic group is e.g. As acrylic acid, methacrylic acid is preferred.
- Suitable anionic (meth) acrylate copolymers of 40 to 60, wt .-% methacrylic acid and 60 to 40 wt .-% methyl methacrylate or 60 to 40 wt .-% ethyl acrylate types EUDRAGIT® L or EUDRAGIT® L100-55).
